Bound in an unwanted marriage, Freya spends her days gutting fish, but dreams of becoming a warrior. And of putting an axe in her boorish husband’s back.

Freya's dreams abruptly become reality when her husband betrays her to the region's jarl, landing her in a fight to the death against his son, Bjorn. To survive, Freya is forced to reveal her deepest secret: She possesses a drop of a goddess's blood, which makes her a shield maiden with magic capable of repelling any attack. It was foretold such a magic would unite the fractured nation of Skaland beneath the one who controls the shield maiden’s fate.

Believing he's destined to rule Skaland as king, the fanatical jarl binds Freya with a blood oath and orders Bjorn to protect her from their enemies. Desperate to prove her strength, Freya must train to fight and learn to control her magic, all while facing perilous tests set by the gods. The greatest test of all, however, may be resisting her forbidden attraction to Bjorn. If Freya succumbs to her lust for the charming and fierce warrior, she risks not only her own destiny but the fate of all the people she swore to protect.
